[0028] Specifically, the inner cavity of the rotating seat 3 is provided with a threaded protrusion, and the top end of the detection tube 4 is fixedly installed with a corresponding threaded block. Through simple rotation operation, the installation or disassembly of the detection tube 4 is quickly completed, greatly shortening the equipment maintenance and adjustment time. At the same time, the threaded connection structure provides stable connection strength, ensures that the detection tube 4 will not loosen and shift during measurement, guarantees the accuracy and stability of water depth data collection, improves work efficiency, and reduces the measurement risk caused by unreliable component connection. At the same time, the limiting clamp 5 is made of plastic, and the disassembled detection tube 4 and extension structure are clamped into the limiting clamp 5. This not only effectively prevents the components from being damaged by shaking during carrying, but also greatly reduces the occupied space of the device through reasonable storage layout, so that the staff can orderly fix the scattered components on the outer wall of the protective shell 1, improving the portability and storage efficiency of the device as a whole.

[0029] Please refer to Figure 1 , Figure 2 Each extension structure comprises a folding rod 601, (such as Figure 1The topmost folding rod 601 slides into the inner cavity of the detection tube 4, and the remaining folding rods 601 are sequentially sleeved from top to bottom, the inner cavity bottom end of each folding rod 601 is fixedly connected with a connecting pipe 602, the outer wall of the connecting pipe 602 is rotatably sleeved with a rotating sleeve ring 603, and the inner cavity of the rotating sleeve ring 603 is rotatably installed with a spring sheet 604 for fixing the unfolded state of the folding rod 601;

[0030] Specifically, the outer wall of each folding rod 601 and the detection tube 4 is provided with a scale line, (such as Figure 2 The outer wall of each folding rod 601 is provided with two groups of insertion grooves 605 for limiting, and the two groups of insertion grooves 605 are symmetrically and uniformly distributed at the upper and lower ends of the folding rod 601, and the outer wall bottom end of the detection tube 4 and each connecting pipe 602 is provided with a through slot 606 for facilitating the shuttling of the spring sheet 604, and the spring sheet 604 is located in the through slot 606, so as to facilitate the spring sheet 604 to pass through the through slot 606 and be connected with the insertion groove 605, when the spring sheet 604 is connected with the insertion groove 605 at the upper end, at this time, the folding rod 601 is in an unfolded state, and is fixed and limited, on the contrary, when the spring sheet 604 is connected with the insertion groove 605 at the lower end, at this time, the folding rod 601 is in a contracted state, and is fixed and limited, by the precise cooperation of the bidirectional insertion groove 605 and the spring sheet 604, the structural stability during measurement is ensured, and the folding rod 601 can be quickly folded during storage, and the operation convenience and functional practicability are considered;

[0031] More specifically, the outer wall of the through slot 606 and the insertion groove 605 is provided with a chamfer, so that the spring sheet 604 can be easily inserted or removed, which ensures reliable locking and facilitates operation, when it is necessary to extend the folding rod 601, the operator only needs to rotate the folding rod 601, and by using the chamfer edge of the through slot 606 and the insertion groove 605, the spring sheet 604 can be smoothly extruded from the insertion groove 605 at the lower end, so that it is retracted to the inside of the rotating sleeve ring 603, and at the same time, the energy storage preparation for the next limiting is completed, after the folding rod 601 is completely pulled out and unfolded, the folding rod 601 is reversely rotated, when the insertion groove 605 and the through slot 606 are coincided again, the spring sheet 604 will instantaneously release the elastic force and be inserted into the insertion groove 605 at the upper end, so that the folding rod 601 is efficiently and reliably repositioned, and the folding rod 601 can maintain a stable and stretched state during the hole exploration operation;

[0032] The inner cavity of each rotating sleeve ring 603 is fixedly connected with a positioning shaft 607 for positioning the spring sheet 604, and the spring sheet 604 is fixedly sleeved on the outer wall of the positioning shaft 607;

[0034] Specifically, the inner diameter of the limiting plate 608 and the sliding groove is equal, and the inner diameter of the connecting pipe 602 is smaller than both, so that when the folding rod 601 is pulled to move and expand, the limiting plate 608 collides with the connecting pipe 602, which reminds the user that the folding rod 601 has been fully expanded. At the same time, the limiting plate 608 and the connecting pipe 602 limit the folding rod 601 to avoid the risk of the folding rod 601 slipping due to excessive movement, effectively improving the structural reliability and operation safety of the folding rod 601 under complex working conditions, and ensuring accurate limiting and smooth sliding.

[0035] Embodiment two: please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , based on the basis of embodiment 1, the calibration structure includes a counterweight 701, the counterweight 701 is threadedly connected with the bottom of the bottommost folding rod 601, the top end of the rotating seat 3 is fixedly connected with a rotating ball 702, the inner cavity of the protective shell 1 is fixedly installed with a clamping pipe 703 for fixing the rotating ball 702, and the rotating ball 702 rotates in the clamping pipe 703. Through the influence of gravity on the counterweight 701, the extension structure and the detection pipe 4 are driven to swing and rotate in the clamping pipe 703 with the rotating ball 702 as the fixed point, so as to realize the purpose of automatically calibrating the vertical state of the detection pipe 4. The rotating ball 702 is externally sleeved with a clamping structure for limiting the rotation of the rotating ball 702;

[0036] The clamping structure includes a rotating ring 704, and the inner sides of the rotating ring 704 are rotatably connected with a push rod 705 through a pin shaft. One side of each push rod 705 is rotatably connected with a clamping plate 706 through a pin shaft, and the two groups of clamping plates 706 are symmetrically and uniformly distributed on the two sides of the rotating ball 702.

[0037] Specifically, the upper and lower ends of the clamping pipe 703 are fixedly connected with the inner wall of the protective shell 1, and a horizontal groove is formed in the center of the clamping pipe 703 for facilitating the movement of the clamping plate 706. The upper and lower dimensions of the horizontal groove are consistent with those of the clamping plate 706, so that the clamping plate 706 can pass through the horizontal groove and directly contact the rotating ball 702.

[0038] More specifically, the top surface of each group of clamping plates 706 is fixedly installed with a moving rod 707 for assisting the stable movement of the clamping plate 706. The top end of the moving rod 707 is fixedly connected with a sliding block, and the inner wall of the protective shell 1 is provided with a moving groove for assisting the linear movement of the clamping plate 706, and the sliding block is located in the moving groove.

[0039] The top surface of the rotating ring 704 is fixedly installed with a bevel gear ring 708, the inner wall of the protective shell 1 is fixedly installed with a motor 709, the output shaft of the motor 709 is fixedly connected with a bevel gear 710, and the bevel gear 710 is engaged with the bevel gear ring 708.

[0040] Specifically, a fixing bracket 711 for supporting the rotating ring 704 is rotatably mounted at the bottom end of the rotating ring 704, and it is fixedly connected to the protective shell 1.

[0041] The working principle of this utility model is as follows:

[0042] First, the user screws the detection tube 4 into the threaded block at the top of the rotating seat 3 to ensure a secure connection. According to the actual water depth requirements, the user adjusts the length of the folding rod 601 at the bottom of the detection tube 4. By rotating the rotating collar 603, the user uses the chamfer of the through groove 606 and the slot 605 to retract the spring plate 604 from the lower slot 605, thereby pulling out the folding rod 601. After it is fully pulled out, the user rotates the rotating collar 603 in the opposite direction to make the spring plate 604 engage with the upper slot 605, fixing the unfolded state of the folding rod 601 to facilitate the expansion of the detection depth.

[0043] During the measurement process, the folding rod 601, along with the detection tube 4, is inserted into the water until the counterweight 701 contacts the bottom. During this process, the counterweight 701, under the influence of gravity, drives the extension structure and the detection tube 4 to swing within the clamping tube 703 with the rotating ball 702 as the fixed point. After automatically calibrating the detection tube 4 to a vertical state, the motor 709 is started to drive the bevel gear 710 to rotate, which in turn drives the bevel gear ring 708 that meshes with it, causing the rotating ring 704 to rotate. Through the push rod 705, the clamping plate 706 passes through the transverse groove of the clamping tube 703 to clamp the rotating ball 702, ensuring that the detection tube 4 is stable and vertical, thereby ensuring the accuracy of the water depth measurement. At the same time, the water depth is determined by checking the scale lines on the outer wall of the folding rod 601 and the detection tube 4. When the water flow is strong, the counterweight 701 is rotated to remove it, and a counterweight 701 of different sizes can be replaced as needed.

[0044] When finally storing, repeat the unfolding operation of the folding rod 601 in reverse, slide the folding rod 601 back in sequence, and after folding, rotate the detection tube 4 to separate it from the rotating seat 3. Use the limiting clamp 5 to fix the disassembled detection tube 4 and the extension structure to the outer wall of the protective shell 1.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
